Generalized Linear Models
ISTE Ltd and John Wiley & Sons Inc (Verlag)
978-1-78630-702-6 (ISBN)
This book provides an overview of the theory of generalized linear models. Particular attention is paid to the problems of censoring, missing data and excess zeros. Didactic and accessible, Generalized Linear Models is illustrated with exercises and numerous R codes.
With all the necessary prerequisites introduced in a step-by-step fashion, this book is aimed at students (at master's or engineering school level), as well as teachers and practitioners of mathematics and statistical modeling.
Jean-François Dupuy is Professor of Applied Mathematics at the University of Rennes and is a member of the Institut de recherche mathématique de Rennes, France. His research focuses on statistical modeling, generalized linear models and duration models.
